[0002] Electric vehicles have been widely applied due to energy saving and environmental protection and relatively low use cost. In practical application, the electric vehicles need to be charged by charging piles. The current charging piles for electric vehicles only have the function of converting alternating current into direct current (the alternating current to direct current module outputs direct current to the input end of the control system of the total power supply of the charging pile, and the control system outputs power supply to charge the storage battery of the vehicle. For commercial charging piles, the charging amount of the vehicle is also counted, and the charging vehicle is charged through charging software), and when charging, the driver inserts the charging gun into the charging port of the vehicle, and the direct current output by the charging pile charges the storage battery of the vehicle.
[0003] The above charging mode meets the needs to a certain extent, but also has some disadvantages due to the structure. Specifically, when the vehicle is charged during the peak electricity consumption period (for example, domestic vehicles cannot be charged during the off-peak electricity consumption period due to time constraints), unnecessary electricity charges will be incurred. In addition, the current charging pile only has the function of converting commercial power into direct current, and cannot use solar cells to charge the vehicle, so it cannot achieve better energy saving effect. In view of the above, it is necessary to provide a device that can effectively use solar energy and off-peak electricity to charge the vehicle. UTILITARIAN CONTENT

The power output end of the charging control circuit, the normally open contact end of the relay J1 and the emitter of the transistor Q1, and the two control power input ends of the relay J4 are connected through wires. The two control power input ends of the relay J3 and the power output ends 3 and 4 of the AC-to-DC power module A3 are connected through wires respectively. The two normally open contact ends of the relay J3, the two normally closed contact ends of the relay J4 and the control system total power input end KZ of the electric vehicle charging pile body are connected through wires.

[0018] Figure 1 、 2As shown, the new charging pile body 1 (because the battery capacity cannot be infinite, the new type is most suitable for home or specific non-commercial area use) works, the AC power to DC power module A3 outputs DC power, or the DC power output by the battery pack G2 to the control system KZ total power input end of the charging pile, after the charging gun is inserted into the vehicle charging socket, the control system outputs power to charge the vehicle battery (for commercial charging piles, it will also count the charging capacity of the vehicle, and charge the charging vehicle through the charging software), during charging, the driver inserts the charging gun into the charging socket of the vehicle, and the DC power output by the charging pile body charges the battery on the vehicle. The above charging pile body is a mature technology, and the working principle and technical solution thereof will not be described again. In the new type, the solar panel G1 generates electric energy under light irradiation to charge the battery pack G2 (the reverse blocking effect of diode VD1 ensures that the battery pack G2 and the power output by the AC power to DC power module A3 will not enter the power input end of the solar panel G1), so that the electric vehicle can be charged by the power output by the solar panel G1 and the battery pack G2 in the future. After the time control switch A2 is powered on, the 3 and 4 pins thereof will output power to the power input end of the AC power to DC power module A3 during the low-power consumption period of the city power every day (such as every night from 23:00 to the next morning at 7:00), and the 3 and 4 pins of the AC power to DC power module A3 output DC power to the power input end of the relay J2 and the normally closed contact end for charging the battery pack G2 (at this moment, the relay J5 is not powered on, the control power input end and the normally open contact end are open, and the 220V AC power will not directly enter the power input end of the AC power to DC power module A3). In actual situations, the solar panel G1 does not fully charge the battery pack G2 during the day, and when the no-load voltage of the battery pack G2 is lower than the minimum charging setting value, the power output by the battery pack G2 enters the triode Q2 through the adjustable resistor RP2 and the resistor R2, which is lower than 0.7V, so the triode Q2 will not be turned on, and the relay J will continue to be in a de-energized state, and the control power input end and the normally closed contact end are closed. Then, the 220V power enters the power input end of the time control switch A2, and the AC power to DC power module A3 continues to charge the battery pack G2. When the solar panel G1 fully charges the battery pack G2 during the day, and the no-load voltage of the battery pack G2 is higher than the minimum charging setting value, the power output by the battery pack G2 enters the triode Q2 through the adjustable resistor RP2 and the resistor R2, which is higher than 0.7V, so the triode Q2 will be turned on, and the negative power input end of the relay J will be low, and the relay J will be energized, and the control power input end and the normally closed contact end will be open. Then, the time control switch A2 and the AC power to DC power module A3 will not be powered on, and the battery pack G2 will stop charging to prevent overcharging and damage to the battery pack G2.
[0019] Figure 1 ,2As shown, when the vehicle is charging, if the no-load voltage of the battery pack G2 is higher than the minimum set value, the power output by the battery pack G2 is divided by the adjustable resistor RP1 and the resistor R1 to enter the triode Q1 higher than 0.7V, the triode Q1 will be turned on to output low level to the negative power input end of the relay J1, the relay J1 is attracted to close the control power input end and the normally open contact end, the power output by the battery pack G2 enters the control system KZ total power input end through the control power input end and the normally closed contact end of the relay J4, so that the battery pack G2 directly charges the vehicle battery (on the basis of closing the power switch S). When the no-load charging voltage of the battery pack G2 is lower than the minimum set value, the power output by the battery pack G2 is divided by the adjustable resistor RP1 and the resistor R1 to enter the triode Q1 lower than 0.7V, the triode Q1 will be cut off and no longer output low level to the negative power input end of the relay J1, the relay J1 loses power and no longer attracts the control power input end and the normally open contact end (the control power input end and the normally closed contact end are closed), the power output by the battery pack G2 no longer enters the control system KZ total power input end through the control power input end and the normally closed contact end of the relay J4, so that the battery pack G2 no longer charges the vehicle battery; at the same time, when the relay J1 loses power and no longer attracts the control power input end and the normally closed contact end, the alarm lamp H (the light emitting surface is located on the front outer side of the charging pile body shell) will be powered on to issue an audible and visual alarm signal (the user can close the power switch S1 at this moment to prevent unnecessary interference caused by the alarm lamp H issuing an audible and visual alarm sound), prompting the user that the battery pack G2 is insufficient and can be directly charged by using the mains. After the alarm lamp H issues an alarm signal, the charging personnel can turn on the power switch S, so that the relays J5, J2, J3 and J4 are attracted. After the relay J5 is powered on, the control power input end and the normally open contact end are closed, so that the AC to DC power supply module A3 is powered on to work; the relay J2 is attracted, the control power input end and the normally closed contact end are open, and the power output by the AC to DC power supply module A3 no longer charges the battery pack G2; the relay J4 is attracted, the control power input end and the normally closed contact end are open, and the battery pack G2 no longer charges the vehicle battery; after the relay J3 is attracted, the control power input end and the normally open contact end are closed, and the DC power output by the AC to DC power supply module A3 directly enters the control system KZ total power input end to charge the vehicle battery (after the subsequent charging is completed, the power switch S is closed).In summary, through the above, the new type based on the charging pile body, in the application, can be charged for the energy storage battery (battery pack) through the solar cell panel, and when the solar cell charging is insufficient, the time control switch cooperates with the detection circuit, the AC power supply to DC power supply module can supplement the energy storage battery in the low valley power consumption period, the charging control circuit cooperates with the output circuit when the vehicle is charging, can first charge the vehicle storage battery through the energy storage battery, and when the energy storage battery is not enough, can switch the mains to charge the vehicle storage battery, thereby ensuring the effective charging of the vehicle, and effectively saving energy and expenditure. Figure 2 As shown, the relay J, J1 is a direct current relay; the relay J5, J2, J3, J4 is an alternating current relay; the diode VD1 model is 6A10; the resistance R1, R2 resistance is 1K; the adjustable resistance RP1, RP2 resistance is 470K (adjust to 220K); the alarm lamp H model is LTE-5061; the battery pack G2 is a lithium battery pack; the time control switch A2 is a time controller with model KG316T, which has two power input terminals, two power output terminals, seven setting keys, respectively operating seven setting keys, and can set the power time output by the two power output terminals.
